DEVELOPMENT OF TOUGH, HIGH-STRENGTH ALPHA-BETA TITANIUM BASE ALLOYS,
Abstract
The addition of varying weight percentages of the substitutional elements Cr, Mo, Mn, Ni, U, and Zr and the interstitial elements O. N, C, and B to the basic alloy, Ti-6Al-6V-2Sn-1/2Fe-1/4Cu, resulted in alloys which exhibited mechanical properties superior to those of the basic alloy. The optimum mechanical properties ranged from 198,000 psi yield strength at 0.1 percent offset, 205,000 psi tensile strength, 5 percent elongation, 14.0 percent reduction of area, and 5.4 ft-lb Charpy V-notch impact energy at -40 F for alloy Ti-6Al-6V-2Sn-1/2Fe-1/4Cu, to 221,000 psi yield strength at 0.1 percent offset, 224,000 psi tensile strength, 11.9 percent elongation, 32.1 percent reduction of area, and 5.9 ft-lb Charpy V-notch impact energy at -40 F for alloy Ti-6Al-6V-2Sn-3/4Cu-3Zr0.015N-0.114 02-0.00217H-0.12C.
